Based on positional observations and measurements of radial velocities, the orbits of 850 wide visual double stars have been determined. The parameters of the log-normal distributions for the histograms of orbital periods, stellar masses, and semi-major axes in astronomical units have been obtained. The eccentricity histogram for binary stars with orbital periods less than 400 years follows a normal distribution centered at e=0.545+/-0.029. For stars with longer periods, this distribution obeys the law f=2e, with accuracy to errors. The mass-to-luminosity relation for stars with well-determined masses is given by: logL_{sun}=4.33logM{sun}-0.11, where L{sun} and M{sun}_ are the luminosity and mass of the star in units of the solar luminosity and mass, respectively.
